Understanding, controlling and improving the flavour of almond kernels. Almond kernels may be sweet, semi-bitter or bitter, with the first two categories marketed as fresh nuts, while the latter are used in processed products such as marzipan. Semi-bitter kernels have a more interesting flavour than sweet kernels and we require tools to breed for this character. The bitter flavour is imparted by amygdalin via the cyanogenic pathway. This project will characterise the genetic control of sweet, ....Understanding, controlling and improving the flavour of almond kernels. Almond kernels may be sweet, semi-bitter or bitter, with the first two categories marketed as fresh nuts, while the latter are used in processed products such as marzipan. Semi-bitter kernels have a more interesting flavour than sweet kernels and we require tools to breed for this character. The bitter flavour is imparted by amygdalin via the cyanogenic pathway. This project will characterise the genetic control of sweet, semi-bitter and bitter flavour, amygdalin accumulation in developing kernels, and key enzymes in the cyanogenic pathway. Almond populations segregating for these traits will be used and the data will be integrated into the Australian almond meiotic map.Read moreRead less
Investigation of almond transformation for self-fertility and virus resistance. This project addresses the long-term goal of the Australian almond industry to produce cultivars that are self-fertile and resistant to Prunus necrotic ringspot and prune dwarf viruses. Both self-sterility and virus infection can result in unreliable and often low yields. Research will address the control of gene expression relating to self-sterility and the introduction of virus resistance, via sequencing of self- ....Investigation of almond transformation for self-fertility and virus resistance. This project addresses the long-term goal of the Australian almond industry to produce cultivars that are self-fertile and resistant to Prunus necrotic ringspot and prune dwarf viruses. Both self-sterility and virus infection can result in unreliable and often low yields. Research will address the control of gene expression relating to self-sterility and the introduction of virus resistance, via sequencing of self-fertility and self-sterility genes, construct development and improved regeneration of transformed almond in vitro without the use of antibiotics.Read moreRead less
Genomics to rust proof the humble oat. This project aims to reduce the impact of the damaging and currently intractable fungal pathogen crown rust (OCR) in Australian oat production. The expected project outcomes are: new sources of enduring high value resistance to OCR, tools to accelerate the use of these resistances, and locally adapted OCR resistant oat germplasm for use in developing profitable oat varieties. The project will use new approaches to tap very recently released genomic resource ....Genomics to rust proof the humble oat. This project aims to reduce the impact of the damaging and currently intractable fungal pathogen crown rust (OCR) in Australian oat production. The expected project outcomes are: new sources of enduring high value resistance to OCR, tools to accelerate the use of these resistances, and locally adapted OCR resistant oat germplasm for use in developing profitable oat varieties. The project will use new approaches to tap very recently released genomic resources and unique oat/ OCR resources assembled over many years. It will lead to responsible stewardship of broadly effective OCR resistance in grazing/milling/hay oats, increasing grower profitability, reducing reliance on fungicides, and underpinning planned growth in our export oat market.

Enhancing phosphorus use efficiency in macadamia for sustainable production. Macadamia nuts are an iconic native Australian product worth $287 million annually at the farm gate. Phosphorus fertiliser management currently threatens price premiums for sustainable production in high value European Union export markets, and ‘social license’ to farm in their densely populated coastal production areas. The project aims to exploit adaptive root and shoot traits for phosphorus efficiency found in Austra ....Enhancing phosphorus use efficiency in macadamia for sustainable production. Macadamia nuts are an iconic native Australian product worth $287 million annually at the farm gate. Phosphorus fertiliser management currently threatens price premiums for sustainable production in high value European Union export markets, and ‘social license’ to farm in their densely populated coastal production areas. The project aims to exploit adaptive root and shoot traits for phosphorus efficiency found in Australian native plants to optimise phosphorus fertiliser management and set the platform for breeding macadamia root stocks/varieties that require less phosphorus fertiliser. The outcome will be a macadamia industry that is able to maintain current market price premiums and maintain social license to farm in coastal Australia.Read moreRead less
Developing Zn-dense, high-yielding wheat by molecular marker technology. The objective of this project is to identify pathways leading to the accumulation of zinc — an important element for human nutrition — in wheat. The project aims to provide biochemical and molecular markers for breeding programs that will facilitate the selection of superior breeding lines for improved human nutrition and seed health. This project builds on studies using a wheat diversity panel with 90 000 gene-based single ....Developing Zn-dense, high-yielding wheat by molecular marker technology. The objective of this project is to identify pathways leading to the accumulation of zinc — an important element for human nutrition — in wheat. The project aims to provide biochemical and molecular markers for breeding programs that will facilitate the selection of superior breeding lines for improved human nutrition and seed health. This project builds on studies using a wheat diversity panel with 90 000 gene-based single nucleotide polymorphism (SNP) markers, where zinc–SNP associations were identified. The project also builds on recent studies that show particular metabolites and macronutrients around anthesis are linked to improved grain zinc concentration at maturity.Read moreRead less
Development of drought tolerant, high protein legume for arid Australia. The aim of this research is to demonstrate the molecular basis of a non-proteinogenic amino acid toxin accumulation by using genomics and genome editing to produce a non-transgenic, protein rich legume. The significance of the outcomes will be a fundamental understanding of how non-proteinogenic amino acids are metabolised in plants and an inexpensive, high-protein feed for the pork and chicken industries thereby reducing p ....Development of drought tolerant, high protein legume for arid Australia. The aim of this research is to demonstrate the molecular basis of a non-proteinogenic amino acid toxin accumulation by using genomics and genome editing to produce a non-transgenic, protein rich legume. The significance of the outcomes will be a fundamental understanding of how non-proteinogenic amino acids are metabolised in plants and an inexpensive, high-protein feed for the pork and chicken industries thereby reducing production costs and increasing profitability. The outcomes from the research are fundamental knowledge of non-proteinogenic amino acid metabolism and turnkey approach to identify, engineer, test and produce value added crops. The benefits of the research are a multi-purpose crop for Australian crop and animal producers.Read moreRead less
